KLINGER E-ST Ultrasonic Flowmeter User Manual

E-ST Ultrasonic Flowmeter
User Manual

Notice Thank you for choosing Model E-ST
This instruction manual contains the important use and operation information of the flow meter. Please read carefully the reference manual before the operation to make your flow meter exert the best performance.
If you make a mistake there will be affected the meter’s working and reduce the meter’s life or cause some malfunctions.

Product component

Inspection should be made before installing the Flow meter. Check to see if the spare parts are in accordance with the packing list. Make sure that there is no potential damage to the enclosure due to a loose screw or loose wire, which occurred during transportation.
Any questions, please contact your representative as soon as possible.

Installation and connect

E-ST needs to install the flow sensor and temperature sensor and clean the pipeline before Installation.
Make sure no dirt, paint, or other stains on the surface of the tube. Then put the bottom parts on the side of the pipe.

When ‘E-ST is installed, the Energy meter is wired.
Connect the DC power and RS485 output.

Panel function

Powering on
As soon as the E-ST Energy meter is switched on, the self-diagnosis program will start to run.

Signal Quality (SQ value)

• value is short for Signal Quality. It indicates the level of the signal detected.
• value is indicated by numbers from 0-99 represents the minimum signal detected while 99 represent the maximum.

Normally, the transducer position should be adjusted repeatedly and the coupling compound should be checked frequently until the signal quality detected is as strong as possible.

Keypad Functions

Follow these guidelines when using the Flow meter keypad:

Setting or display mode, when it is setting mode, that can return to the previous menu, and scroll up and down to select the menu, when press move to next digit, press()and the numbers scroll from 0 to 9, you can select the number. Press to confirm.

Setup menu

Press will display Setup menu.

The following options are available (by or buttons)

Setup Menu – pipe parameter

Press)
Select .Pipe parameter, then display:

The following options are available (by ·or buttons)
0. Outer diameter
1. Wall thickness
2. Material: Move · or ·can option PVC, Carbon steel, Steel, Copper pipe.
3. Fluid type: Move or an option Water, Sea Water, Oil…etc.

Setup Menu – System setting

Press , Select 1. System setting, then display:

The following options are available (by(·)or(· buttons)
0. System unit: Move or an option Metric, English.
1. Flow rate unit: Move or can option m3Ih, LPM, GPM.
2. Total unit: Move· or·can m3, L, GAL.
3. Totalize RESET: AII parameters are reset, Press , move, or arrow to select “YES” or “NO After “YES is selected.

Time set

Generally, it is unnecessary to modify the date-time as the system is provided with a highly reliable perpetual calendar chip.

System lock

Once the system is locked, any modifications to the system are prohibited, but the parameter is readable. “Unlock” using your designated password. The password is composed of 1to 4 numbers.

System INFO

System INFO: Display the serial number (SN) of the meter. This SN is the only one assigned to each flow meter ready to leave the factory.
The factory uses it for file setup and for management by the user. Set zero: Press ; reset Zero Point” which was set by the user.
Manual Totalizer: The manual totalize is a separate totalize. Press to start, and press to stop it. It is used for flow measurement and calculation.

Display dir

Can choose the direction of the display, convenient to observe the measurement data.

Setup Calibration

Press .Select 2. Calibration, and then display:

0. Scale factor

Refers to the ratio between “actual value” and reading value”. For example, when the measurement Is 2.00, and It Is Indicated at 1.98 on the instrument, the scale factor reading is 2/1.98. This means that the best scale factor constant is1.01.

1. Set zero: Press ; reset ‘Zero Point which was set by the user.
   

2. Low flow cut: The flow rate falls below the low flow cutoff value.
   The flow indication is driven to zero. This function can prevent the flow meter from reading flow after a pump as shut down but there is still liquid movement in the pipe, which will result in a totalization error.
   Generally, 0.03m/s is recommended to enter as the low flow cutoff point.
   The low flow cutoff value has no relation to the measurement results once the velocity increases over the low flow cutoff value.

3. Manual zero

The seldom-used calibration method is suitable for experienced operators to artificially input an offset superimposed on the measured value
in order to obtain the true value when other calibration methods cannot be used well.
For example:
Actual measured value =250 m3/h
The offset valve =10 m3lh
Meter display =240 m3/h
In general, this value should be set: to “0”.

Setup Menu – Output

Press .Select 3. Output setting, and then display:

0. RS485 setup

The window is used to set the serial port. It connects with the equipment of its serja! port set of parameters must match.

1. Alarm value(Option)

Enter the low alarm value; any of the measured flow, which is lower than the low value, will activate the alarm in the OCT hardware or relay output signal.
Enter the high alarm value; any of the measured flow, which is higher than the high value, will activate the alarm in the OCT hardware or relay output signal.
